6 Claims.

This invention relates to certain new and useful improvements in the fliers employed in connection with spinning machines and the like.

It has for one of its objects to provide a flier structure which is so designed and constructed that those parts thereof which are subject to wear may be readily replaced without discarding the whole ier, thereby affording a material saving to the ier users.

Another object of the invention is to provide a flier which is simple, light and inexpensive in construction, which is efcientin operation, and which is further so designed as to prevent the flier overrunning or continuing to revolve after the bobbin has come to rest.

In the accompanying drawingz;

Figure 1 is a fragmentary front View of a portion of a spinning machine showing my improved nier applied thereto. Figure 2 is an enlarged top plan view of the flier and associated bobbin. Figure 3 is a fragmentary vertical section taken on line 3 3, Figure 2. Figures 4 and 5 are horizontal sections taken on the correspondinglynumbered lines in Figure 3. yFigure 6 is a side elevation of the flier-base hub or bearing member.

Similar characters of reference indicate corresponding parts throughout the several views.

The invention is applicable to 'spinning lmachines of any suitable and well known construction, l indicating the bobbin spindle and'l l the take-off bobbin mounted thereon. The thread or yarn from the bobbin extends upwardly through the flier wires I2 and i3 mounted on a holder or iiier body applied to the bobbin spindle and thence passes upwardly through a guide or centering eye lli to a take-up spool (not shown). The bobbin shown is of the type used with fliers of the eccentric type and has a recess l5 in its top containing an inverted cup-like member I6 having an opening l'l therein arranged concentric to the aXis of the bobbin spindle.

The hier body preferably consists of an attaching sleeve or journal member I8 adapted to be fitted over the bobbin spindle and made of any suitable metal. At its lower end this sleeve has an eccentrically-shaped flange I 9 adapted to be passed through the cup-opening Il during the application and removal of the flier body to and from the spindle. Spaced above this eccentric flange is an annular flange 2l) and formed in the sleeve preferably in the plane of this flange is an internal annular groove 2l. Encircling the spindle I0 and fitted in this groove, is a substantially circular wire spring 22 which, as shown in Figure 5, is adapted to engage the the wire-base 2li is attached. This bearing mem- 10 ber is preferably made of fiber and is detachably mounted on the sleeve for limited axial displacement, the upper end of the sleeve having a de' tachable split band 25 applied theretoI which `forms a shoulder for limiting the upward disl5 placement of the bearing member during its rotation. When it is desired to remove the bearing member from the sleeve, this can be readily effee-ted by merely removing the band 25 therefrom.

To prevent the flier overrunning after the bobbin has come to rest, I provide the bearing member 23 with a brake element 26 substantially in the form of a pin which is guided in a radial opening in the .bearing member and which is 25 adapted for frictional or braking contact with the contiguous surface of the sleeve i8. A retaining spring Ell is seated in an annular groove 28 in the bearing member and extends over and bears against the outer end of the brake 2t to 30 constantly urge the latter into frictional contact with the sleeve i8 and resist outward displace'- ment oi" the brake pin from the bearing member.

l claim as my invention: n

1. A flier for spinning machines and the like, comprising a sleeve adapted for attachment to a bobbin-spindle, a bearing member detachably mounted on said sleeve, a'wire-base mounted on said bearing member, and yieldable clutch means disposed between said sleeve and the spindle and 40 constituting a driving connection between such parts. p

2. A flier for spinning machines and the like, comprising a sleeve adapted for attachment to a bobin-spindle and having an internal annular groove therein, a yieldable clutching element encircling the spindle and tted in said groove and constituting a driving connection between the sleeve and the spindle, a bearing member detachably mounted on said sleeve, and a wirebase mounted on said bearing member.

3. A flier for spinning machines and the like, comprising a sleeve adapted for attachment to a -bobbin-spindle and having an internal annular groove therein, a substantially circular wire spring tted in said groove about the spindle and in .bearing contact with the latter and said sleeve to provide a driving connection between such parts, and a wire-base rotatably mounted on said sleeve.

4. A flier for spinning machines and the like, comprising a sleeve adapted for attachment to a bobbin-sp-indle, a bearing member detachably mounted on said sleeve, a wire-base mounted on said bearing member, and a braking means applied to said bearing member for engagement with said sleeve.

5. A flier for spinning machines and the like, comprising a sleeve adapted for attachment to a bobbin-spindle, a bearing member detachably mounted on said sleeve, a wire-base mounted on said bearing member, a braking means applied to said bearing member for engagement with said sleeve, and yieldable clutching means disposed between said sleeve and the spindle and constituting a driving connection between said parts.

6. A flier for spinning machines and the like, comprising a metallic sleeve adapted for attachment to a bobbin-spindle, a, ber bearing member loosely mounted on said sleeve and having a wirebase borne thereby, a spring clutchingelement disposed substantially concentrically of and between said sleeve and the spindle and constituting a driving connection between such parts, and a braking element applied to said bearing member for frictional contact with said sleeve and including spring means for urging it into contact with the latter.
